Parvovirus B19 (Human), IgG, IgM

This test measures specific antibodies in your blood that your immune system creates to fight Parvovirus B19. By detecting these markers, the test helps show whether you have an active infection, a recent infection, or immunity from a past exposure. Doctors often use this information to investigate the cause of symptoms like joint pain or the distinctive rash associated with Fifth disease. However, a positive result only indicates exposure to this specific virus and does not determine the severity of the illness.
